Grade 5 Science

Explore the diversity of organisms through classification and taxonomy, from the six main kingdoms to species, including vertebrates and invertebrates, vascular and nonvascular plants, fungus, bacteria, and protists.

Explore how vascular and seedless plants grow, reproduce, and transport resources, from moss life cycles and spore-based alternation of generations to flower parts, pollination, seed germination, and plant anatomy.

Explore how vascular plants move water via xylem from roots to leaves. Phloem transports sugars from leaves to the rest of the plant.

Discover how photosynthesis uses sunlight, water, and carbon dioxide to make sugar and oxygen. Learn how respiration in plants and animals, powered by mitochondria, converts sugar to energy.

Explore the human body by outlining organ systems and examining the digestive, respiratory, circulatory, and excretory systems. Learn how cells form tissues and organs and how these systems work together.

Explore the digestive system from mouth to large intestine, learning how chewing, saliva, esophagus, stomach enzymes like pepsin, liver and pancreas juices, and absorption into blood power our body.

Explore how the respiratory system uses the lungs, diaphragm, trachea, bronchi, and alveoli to exchange oxygen and carbon dioxide, powering cells through respiration.

Explore how the heart powers the circulatory system, pumping oxygen rich blood through arteries to the body and returning deoxygenated blood via veins, with capillaries, atria, and ventricles.
